SPINNING FRAME AND THE LIKE.

Application filed February 10, 1921. Serial No. 448,759.

and the like, and the object thereof is to' provide simple and eflicientmeans to stop the feeding of rovings through the drawing rolls after thethread or yarn has been broken. My present invention is designed as animprovement upon that illustrated and described in my prior patentapplication, filed July 16, 1919, Serial No. 311,221. One of the mainobjects of the present invention is to provide simple means forautomatically resetting the device or gripping means which severs orgrips the rovings whereby the same are positioned for the next operation without dependence upon the care and forethought of the operator.The construction and arrangement are such that this device is reset bythe act of the operator in rethreading and restoring the eye or guide tonormal position.

Another object of my invention is to provide simple and efficient means,acting both to doff all of the bobbins shuultaneously in asection and tocollect the dust and lint at the front of the board of table.

My new structure embodies other novel and advantageous features ofconstruction which will be apparent from the description hereinaftergiven.

In the drawings Fig. 1 is a vertical scition through the spinning frameembodying my inventionand also showing the dotting means operated; Fig.2 a detailed view of a part of the controlling means: Fig. 31 a lan viewof the parts shown in Fig. l; *"ig. 4 a view similar to Fig. l butshowing the severing and gripping incansauul the controlling means inoperated position;

Fig. 5 a perspective of the severing dos vice and a part of thecontrolling means in a position to reset such device and Fl}!- 0 asimilar view but showing said dcvice reset.

The spinning frame may be and is shown as of the ordinary type.comprising suitable frame members including a board or table 10 on whicharc arranged a large number of spinning units in the usual manner. Thespinning mechanism propcr includes a spindle l1 rotated by suitablemechanism (not shown) on which is mounted a spool 12 to receive thethread or yarn, a ring board 13 constructed and arranged to bereciprocated vertically in order to carry the ring 14 and the traveler15 thereon longitudinally of the spool during the winding operation.

The usual drawingrolls are employed,'

the same comprising three pairs of rolls l6, 1"? and 18 revolved atprogressively increasing speeds so that the rovings are drawn orlengthened by the relative movement of the fibers between successivepairs of rolls. A scavenger roll 19 is also emplayed to cooperate withthe rolls 18. Supply bobbins 20, of which there are com monly 2 for eachset of drawing rolls and spinning mechanism; are mounted behind thedrawing rolls in osition to feed the rovlngs thereon to the ite of therolls.

Rovings 21 and 22 from the supply bobbins are carried through a trumpetguide 23 to the first pair of drawing rolls 16,'thence through the rolls17 .and 18 to the eye or guide 24 which is arranged in the axis ofrotation of the spindle 11 and from which the thread or yarn is carriedthrough the traveler 15 and thence to the spool 12. This trumpet guideis mounted upon the usual reciprocating slide bar 25 which extendslongitudinally of the frame and is common to all of the sets of drawingrolls, such slide being reciprocated by suitable mechanism (not shown).The horizontal bar 26 performs its usual function of supporting thehearings of the drawing rolls.

ll.\ccpt for the specific form and mounting of the thread guide 24.hereinafter described in detail. the mechanism as thus far set forth isthat which is common to most spinning machinery and therefore need nothe further described.

Referring to my stop mechanism. the same compriscs a device for severingor gripping the rovings after one or more of them or the thread or yarnhas bccnbrokcn. and also controllingmeans operating in connection withthe guide 24 and dependent upon the continuity of the thread in suchguide. As shown this device consists of a plate or rack 27 having a pairof combs 28 projecting therefrom and adapted to fit upon opposite sidesof the bar 26 when such plate is inits horizontal or operated position,with the result that the rovings will be gripped lictwecn the combs andthis bar 26 and sevcrcd ill or broken by the draft of the rolls. Theplate 27 is pivoted to a bracket 25) which is secured orii'cljllfvitlllly gripped to the bar 26 in suitable manner as by meansof set screws 30. In practice these plates are provided. in pairswollting in opposite directions and pivoted to a single bracket .29 asshown in Fig. :3, so that a single bracket with the two stop deviceswill serve two adjacent spinning units, The plate 27 is provided with aprojection such as a pin 31, located in a certain n'edctermined positionon the inner or lower face of the plate, in the present instance at oneside thereof and in the lower portion towards the pivotal point of suchplate. suchipin being provided for the automatic resetting of thesevering de vice hereinafter explained.

Referring to the controllingineans, the same carries at its forward endthe guide 24 and at its rearward upward and a device cooperating directwith the pin 31 for the resetting operation and with the plate 27 tohold the latter in its'inoperative )0- sition but ready to operate. Asshown t is guide is of the usual variety but is not secured to any fixedsupport but to said controlling device. In the present instance the stemof this guide is adjustably connected by means of the sleeve 32 and setscrews 33 to a rod 34 having a right angled vertical portion 35 and ahorizontalportion 36, the latter being pivotally connected in suitablemanner at 37 to a substantially horizontal rod 38 which is suitablypivoted upon the board 10 as at 39. The rod 38 carries at its rearwardend a weight 40 adjustably secured thereon in suitable manner as bymeans of the set screw 41. This rod 38 passes through and is secured toa horizontal and enlarged pin or. cylinder 42 to whose end there issecured a substantially vertical rod 43 carrying at its uiperend anenlarged pin or small 'cylin er 44 adjustably secured to the rightangled horizontal portion 45 of the rod 43 in suitable ma er as by theset screw 46. i The control ing means is preferably so adjusted as to beinjsnbstantial balance or equilibrium and the pressure and friction ofthe threul or yarn through the guide is sutlicient to hold saidcontrolling means in its normal or set position W'hen, however, thethread breaks such pressure on the guide will be relieved and thevibration of the spinning frame will serve to cause the controlling'means to tilt rearwardly to the poshtion shown in Fig. 4. Previously thecylinder 44 had been hearing against the inner or lower face of theplate 27 but the vibration of the frame in such space of time causes therelative movement of such cylinder 44 backward while in frictionalcontact with such face of the plate until it clears such plate whereuponsuch cylinder, acting an incident thereto, the guide 24 is restored toits normal position, previous to which the operator has turned the plate27 upwardly to the inoperative position shown in Fig. "hen the guide :24and the entire controlling: meanr are tilted hack to their normalposition the curved surface of the cylinder ll acting as a cam on thesimilar curved surtao of the pin 31 will tilt the plate 27 to theoperative position shown in Fig. (lat which time such cylinder will takeits position in the path of the plate and sustain it in said position,ready for operation by dropping by gravity.

By balancing the controlling means no additional pressure or friction isapplied to the thread but it is evident that by slightl adjusting theweight 40 rearwardly. such controlling means'may be overbalancedbackwardly without applying any undue additional pressure to the thread.In this event the vibration of the machine need not be relied upon butthe over-balance may be availed of either alone or coupled with theaction resulting from vibration.

Also in respect to the structure shown in my previous patent applicationa posi tivc impulse may he iven to the controllinp means in order torefizase the latch arrange ment between it and the severing device, suchimpulse being provided by means of the, cam 47 carried by thereciprocating bar 25 and adapted to contact the vertical rod 43 andthereby displace it or move it backwardly slightly whereupon theoverhalance thus produced in the'controlling means will take care of theremainder "of the tilting movement.

At the front cndof the table or board I provide a horizontal plate orboard 48 which is of sufficient. length to take care of the. section ofspinning units. This board is pivoted in suitable manner as at 49 to thevertical board 50 of the frame and the same is provided at its frontwith a vertical flange 51, thereby providing a horizontal channel 52which is adapted to collect dust and lint resulting from the spinningoperations. The construction is such that this channel may be readilycleaned in any suitable manner even while the spinning operations areproceeding. This board 48 has a pivotal movement upwardly and the.construction and arrangement are such that the flange 51 willsimultaneously contact the controlling means for all of the units of asection and will throw the same upwardly and also hold them upwardly asindicated by the dotted lines in Fig. l. for which purpose the front endof the controlling means,

that is the front rod thereof, is pivoted at 37. To prevent this actioncausing the severing means to drop into operated position the lockmembers are turned, to the position shown in dotted lines, by anysuitable means; thus locking the rod 43 against the bar 26. therebyretaining the plate 27 with its combs 28 in operative position.
